6 Claims.

The present invention relates to detailed reatures of improvement in arbors for supporting wire bundles or coils to facilitate placing them in annealing apparatus and for handling them after annealing.

The invention will be fully apparent from the following detailed disclosure when read in connection with the accompanying drawings and will be defined with particularity in accordance with the requirements of the patent statutes in the appended claims.

In the drawings:

Figure 3 is a plan view of the upper end of the apparatus of Figure 2; V

Figure 4 is an inverted plan of Figure 2;

Figure 6' is an enlarged detail of the base portion of the arbor with parts broken away and shown in section in the interest of clearness;

Figure '7 is a view partly in side elevation and partly in section of an alternative embodiment of the invention;

Figure 8 is a top plan view thereof Figure;9 is a horizontal section on line IX-IX of Figure 7; and

Figure 10 is a plan view of a supporting plate I detachably associated with the arbor of Figure 7.

Referring first to the embodiment 01' the invention shown in Figures 1 to 6, inclusive, the numeral Ill represents a base casting of conventional type such as used in annealing furnaces for the treatment of coils of wire. The numeral l2 represents a hood or cover adapted to enclose a plurality of superposed coils of wire, such as indicated at M, which are to be annealed.

The present invention relates to details of'construction or design and arrangement of an arbor for positioning the superposed coils of wire. The improved arbor of Figures 2 to 6, inclusive, includes a circular base plate l6 to the underside of which there is welded or otherwise secured a plurality of sets of bars l8-l9 which are arranged in pairs and which are spaced apart by inclined inner spacer members 20 and outer spacer members 22. The bars I8-l9 are united to the underside of the base plate It by fillets of weld metal, such as indicated at 24. Thus the several pairs of bars l8-l9 form spider-like feet for the arbor base plate.

Rising from the upper face of the base plate there are a plurality of bars which are preferably of T-shape in cross section. These bars are indicated at 26 and each includes outer flanges 28 which are bent to conform substantially approximately to the radius of a circle which would enclose all the uprights. The uprights being of T-shape in cross section are provided with inwardly extending webs 30.

The upper extremities of the flanges 28 of the T are arched inwardly, as indicated at 32,

- and the flanges at their inner extremities are uprights meet on the radial lines, such as indi-- pointed so. that the adjacent edges of juxtaposed cated at 34 in Figure 3. Similarly, the webs v30 are arched inwardly and the inner extremities of the webs are beveled so as to meet in a line corresponding to the central longitudinal axis XX of the arbor. The meeting portions of the webs and flanges 28 and 30 of the .uprights are welded together at their upper contacting portions so as to thus form a rigidified skeletonlike structure. At their lower extremities the uprights are welded, as indicated at 36, to the base plate l6.

As shown in Figure 5, a transversely extending plate 38 bridges the space between two oppositely disposed T-shaped uprights. Other plates 40, 42, 44 and 46 are welded to the webs of the other T-shaped uprights and the inner ends of these plates are brought into abutment with the plate 38 and welded thereto, as shown in Figure 5. The plates 38 and the several plates 40, 42, 44 and 46 serve the double function of rigidifying the arbor structure and dividing the space surrounded by 'the coils l4 into a plurality of separate flue-like compartments.

Located above the base and below the lower extremity of the partition plates 38, 40, 42, 44 and 4.6 stifiener bars 48, 50 are provided. These bars have abutting central portions, as .indicated at 52, 54 and they are welded to one another, as indicated at 56. The outer extremities of these barsare welded to the webs of the uprights, as shown. This construction serves to rigidify the base portion. At spaced intervals we also provide a series of outer reenforcing bars, such as indicated at 58 and 60, these bars serving to connect the outer flanges of the adjacent T-shaped members, as shown. A united skeleton structure is thus provided which may be made of comparatively light-weight and which Yet will be possessed of sufllcient strength to withstand the rigors of rigidifying the structure at the base.

crane with the upper extremity of the arched portion of the upright bars.

In the modification of the invention illustrated in Figures 7 to 10, inclusive, the base plate 62 has welded thereto a plurality of uprights 84 of T-shape in cross section, Located centrally of the base there is a short pipe-like section 86 and a "plurality of radial bars 68 are welded at their inner ends to the pipe and at their outer ends to the webs of the upright members, thus Suitable openings III are formed in the base to permit the circulation of gas or heated air therethrough. A detachable coil supporting plate 12 is provided with a plurality of notches 14 which fit over the outer flanges of the upright members, this member-providing an enlarged supporting surface for the-bottommost coil positioned by the arbor.

At a plurality of points spaced at different elevations, such as indicated at 16, there are provided reenforcing bars which span the spaces between the adjacent webs of the uprights. These reenforcing bars therefore jointly form a substantially polygonal outline.

In the embodiment of the invention illustrated, since there are six T-shaped uprights shown, the bars 16 jointly conform approximately to a hexagon. Similarly, an octagonal. figure would be defined in a case where eight uprights were employed.

In the embodiment of the invention shown in Figures 7 to 10, inclusive, instead of arching over the upper extremities of the uprights and welding themdirectly to one another, we provide a top plate 18 to which -.the upper extremities of the uprights are butt welded. This top plate is formed with a central opening 80 which at the center is reenforced by a' ring 82 welded thereto as shown.

A feature common to both embodiments of the invention illustrated is that the arbor comprises a base plate with a plurality of T-shaped uprights welded thereto, these uprights being braced together intermediate their ends. Such an arrangement provides a light-weight coil position-.

ing structure of great strength which will adequately resist the stressesto which apparatus of this character is subjected.

In both embodiments of the invention described, all component parts of the arbor are made up of stock steel parts, such as rolled steel plate used in the base and rolled steel flange members, such as the Ts used for the uprights While we havedescribed quite precisely two alternative embodiments of the invention, it is 1 contemplated that various modifications and suband means connecting the uprights together at and rolled steel bars used for the various reenforcements. Thus the skeleton construction can be produced economically and the parts fabricated by comparatively inexpensive welding operations.
